SPECIFICATION forming part of Letters Patent No. 410,218, datedSeptember 3, 1889.

' Application filed April 23, 1889. Serial No. 308,289. (No model.)

To @ZZ whom may concern,.- i

Be it known'thatl, IRA WALLACE SYL- VESTER, a citizen of the UnitedStates, residing at Palmetto, in the parish of St. Landry and State ofLouisiana, have invented a new and useful Plow, of which the followingis a specification.

This invention relates to that class of plows 4 spective view of a plowequipped with my improvement. Fig. 2 is a vertical transverse section. jFig. 3 is a horizontal sectional View taken on the line of Fig. 2. Fig.lis a detail view in perspective of the parts constituting my invention.

The same letters refer to theisame parts in all the Iigures.

A designates the beam, and B the standard, to which the doublemold-board C is at-t tached in any suitable manner. i

D 1s the lister, which extends rearwardly from the foot of the standard,and which comprises two vertical plates E E, the front ends of which maybe formed integrally with or suitably connected to the foot. of thestandard. w l

F designates `my improved guide-plate, which is arranged verticallybetween the listerplates E E, between which the front end of saidguide-plate is secured upon a pivotal bolt G. The rear end of theguide-plate F is secured by means oi the heel-bolt H of theV lister,which extends transversely "through the plates E E and F, and to whichthe lower end of the ad j listing-brace I is also pivotally connected.The said adj listing-brace may i `be suitably connected with the beamofv the plow; but it forms no part of my present invention.

The front or cutting edge of my improved adjustable guide-plate F maybev either rounded or squared, as shown, respectively, in full and indotted lilies in the drawings To receive the pivi otal bolt G and theheel-bolt H, the said plate", F may be provided with transverse perfora-`tions J, or with slots K, extending to its upper edge,` in order. toenable it to be readily removed by merely loosening the nuts" on the j isaid bolts. It is obvious` that when the slots K are used the plate FAmay be easily adj usted vertically to any desired height. When iperforations J are used, I prefer to provide a series of suchperforations for the. passage of the heel-bolt H, in order to `enablethe rear i or heel end of the said plateF to be lconveniently adjusted.`

From the foregoing description, taken in` connection with the drawingshereto annexed,

the operation 'and advantages of my invention will be readily understoodby those@ skilled in the artto which it appertjains. -In plows of theclass to which` myinvention be longs the double mold-board and theabsence of a landside render it ditiicultto guide the i plow in a trueline, andeven when the ordinary lister is used it is always more or lessliable to swerve out ofthe line of the draft whenever exceptionallyloose or hard por-A tions are encountered in the soil, thus making .l acrookedjfurrow and greatly increasing` the draft. By my invention theguide-plate extends downwardly from` `the lister and into the soil,thereby steadyingthe plow and pre- .venting it from moving In a doubleplow, the combination of the standard carrying the moldeboard, thelister-A platcs secured to and extending rearwardly from the foot ot'said vstandard,the guideplatc having a cutting-edge and mounted ad-`justahly between said lister-plates, and the adjusting-brace connectingthe heel ends of the latter with the `plow-beam, substantially as setforth. i

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses. i
